BRAlD-FEEDING MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent 110,568,387, datedSeptember 29, 1896.

To all whom it may concern.-

Be it known that I, GEORGE W. \VEIss, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvementin Braid-Feeding Mechanism for Bonnaz Sewing-Machines, of which thefollowing is a specification.

My invention relates to an improvement in braid-feeding mechanism forBonnaz sewingmachines, with the object in view of providing for feedingbraids of all usual sizes freely down within the tube in which theneedle operates while retaining the advantages of the universal feed.This object is accomplished by locating certain of the elements of theuniversal feeding mechanism at one side of the needle-tube, by replacingthe ordinary needle-tube by one of larger size, and by placing thefeed-regulating gear off to one side to correspond with the new positionof the said elements of the feeding mechanism.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure l is an end view of the machine,showing the mechanism in position for use. Fig. 2 is a side View of themechanism at the end of the overhanging arm of the machine and of aportion of the overhanging arm, and Fig. 3 is a transverse sectionthrough the overhanging arm of the machine at the point where thefeed-regulating gear is connected with the shaft which has heretoforebeen employed for changing the feed. Fig. 4 is a sectional sideelevation of a portion of a sewingmachine, illustrating the mechanismfor operating the two shafts D and cl.

As my present invention applies only to the structure and arrangement ofthe parts at the end of the overhanging arm and along the arm, I haverepresented only so much of the machine as is essential to show thefeatures of my present improvement, it being understood that the machineis one of the wellknown type commonly called the Bonnaz braid-machine.

The overhanging arm is denoted by A. At its end there is located in theposition in which the combined needle and feed-tube ordinarily occupiesan enlarged tube B, in which the needle operates, as is usual, the tubeB being of such size as to readily admit the passage therethrough ofbraid of all usual sizes, including very wide braid, which it would beimpracticable to undertake to force through the ordinary tube of theBonnaz machine. On the lower end of the tube 13 the verticallymovablepresser-foot b is located and is operated by the vertically-movable bar0, driven by a cam c, operated by a drive-shaft D, extending through theoverhanging arm A, as is usual. The end of the arm has projectingupwardly therefrom a' supporting-bracket E, in which is mounted theframe 6, carrying the braid-supply spool e, as is common, the support abeing provided with gear 6 intermeshing with gear f on the upper end ofthe spindle F, the lower end of the spindle F being provided with gearf, which intermeshes with gear I) on the tube B, andthis latter gear, bymeans of intermediate gear G, being connected with gear 9 on thefeed-shaft H, so that the braid supply spool 6 may be turnedsimultaneously with the turning of the feed shaft and tube B to causethe braid to be fed flatwise in the direction of the feed, whatever maybe the direction given to said feed.

The feed-shaft H (which may be in practice the hollow tube in which theneedle ordinarily operates and through which the braid is commonly fed)is set out of its ordinary position, (which is here occupied by theenlarged tube 13,) and,without materially changing its structure or theoperation of the parts thereof, it is supported by the side of thedepending feed bar I, having the feed-foot i, and opposite the tube B.The shaftH is supported in position by suitable brackets screwed 'to theend or head of the overhanging arm A.

On the shaft H there is fixed a support for the vibrating lever L,arranged longitudinally of the shaft H and so mounted as to vibratetoward and away from the shaft. A camsleeve K is fitted to slide up anddown on the shaft H, and in so doing to engage one arm of the vibratinglever L and thereby cause its opposite arm to move toward or away fromthe shaft H. The sleeve K is moved up and down on the shaft H by meansof an arm 7c, loosely engaged at one end with a groove, at the top ofthe sleeve K, and at its opposite end conneeted with avertically-sliding bar 70, operated by a cam c, actuated by thedrive-shaft D. The lower arm of the vibrating-lever L is connected witha ring or collar Z, loosely surrounding the shaft H and connected withthe feed-bar I. As the vibrating lever L is rocked by the slidingmovement of the sleeve K it will cause the ring or collar Z to move to alimited extent in a plane transverse to the shaft H and willtherebyimpart the horizontal movement to the feed-foot 'i.

The feed-bar I is lifted at proper intervals by means of avertically-reciprocating bar M, operated by an arm 0 actuated by a camon the shaft D. The direction of the feed is changed at pleasure bymeans of the shaft N,

located exterior to the arm A and extending alongside of it, one end ofsaid shaftN being provided with bevel -gear 11, which intermeshes withbevel-gear h on the shaft II, and its opposite end is provided with geara, which, through an intermediate gear 92 e011- nects with gear a on theshaft (Z, which ordinarily extends along within the arm A and isoperated by the operator at the machine to change the direction of thefeed.

To provide a machine of ordinary structure with the braid-feedingdevices hereinbefore described requires but a comparatively small amountof labor and expense, the old needle and braid-tube being utilized inthe new position as a feed-shaft and the shaft for changing thedirection of the feed being utilized and made to subserve the samepurpose by gearing it with the supplemental shaft N on the extension ofthe arm A.

with the frame thereof comprising an overhanging arm, of stitch-formingmechanism, a rotary vertically-reciprocatin g braid-guide, a rotarybraid holder, a universal feeding mechanism including among its elementsa rotary shaft carried by but offset from said arm, means foroperatively connecting said shaft, holder and guide, means for changingthe direction of the feed movement including two parallel rotary shaftscarried by said.

arm, means for connecting and operating said two shafts, and means forconnecting one of said shafts to the said shaft of the feedingmechanism, whereby when the feed movement is changed the position of theguide and holder will also be changed.
